Hi Miklos, what surprises me a bit is that you're introducing a new block scheduling semantic in an OOT – wouldn't you have to modify the scheduler to make it do things differently when encountering a tagged_stream_block2 ? Also, maybe we'd want to have a short chat about what your application ne

Hi Rui, so, what does your software /do/ to transmit samples? What is the sampling rate you're working at? U and L are, as you noted, usually caused by computational insufficiency of the computing platform, but that might have many reasons, not only CPU. Best regards, Marcus On 07/30/2017 05:0

Hi All, Ok, I found the way to do it and want to report for others who run into this. We have to trick SWIG thinking that those virtual functions are not there. This is done in tagged_stream_block.i within GnuRadio like this: class gr::tagged_stream_block : public gr::block { protected: tagged

Dear all, Sorry for the delayed response. As per Bastian's suggestion, I've managed to use the higher level block with the WiFi PHY Hier block included to successfully send data through the set-up. If anybody runs into the issue of using the WiFi PHY Hier block in the future, please look to the lo

Hi All, It seems that no one really has the SWIG expertise. Just to reiterate, if I copy tagged_stream_block from GnuRadio into my OOT, and rename it, it has the exact same compile problem. Now I wonder if GnuRadio has some magic with the SWIG generation, maybe the base blocks are hard coded somew

Hi there, I'm using USRP X310 and the host is Dell OptiPlex 7040. The application is built using GNURadio companion 3.7.10.1 trying to transmit using both the daughter boards. When two channels transmit the same file, the transmission can last for a while before producing U and L and get stuck.
